Makes checking SG easyBy RDMon 2/20/2015

I've had one of these for a year and it has worked very well. I recently added a second tank and a water mixing station. The first one worked so well and carrying it back and forth between the house and my shop got old so getting a second one seemed like a good idea. This is easy to calibrate and use which makes it quick and easy to keep an eye on the SG for my tanks and new water mixes. Highly recommended!

The build quality of this unit is aces. Works like a dream... As a new to the hobby reef keeper, I have to say I have nowhere to go but down after using this refractometer. This is the top.. You deserve it, order one now, you won't be disappointed. Get the case too as this device is worthy of the love.

I love technology, especially when it works. I use this refractometer as my primary tester. Extremely easy to use and calibrate.

Way too easyBy Paulon 12/30/2014

Should of used this earlier, way easy to use and very accurate readings. you can use the available three readings with a touch of a button and no more trying to see the line between marks. You won't regret buying this. I have retired my handheld refractometer now. Just make sure you rinse your pipet in freshwater so you don't get salt build up and throw your readings off.

don't know why i didn't do this earlier - so much better than light refractometer and easier. much more accurate readings.

I have used this quite a bit now and I do find it to be accurate. I find that you can calibrate with either RODI or Distilled water and it doesn't make a difference with the results.

The reason I don't give it 5 stars is due to the 1 ppt offset. To get an accurate 35 ppt level in your aquarium, the Milwaukee will display 36 ppt. I have verified this with two different calibration fluids and comparing to a Pinpoint and a Tropic Marin High Precision Hydrometer.

But once you know the offset, the readings are accurate and it's simple to use.

Best refractometer!By Jimon 12/19/2014

Don't waste your money on any other product. Simple to use, always accurate, functional, easy to read, and more fun to use than other methods. Spend your money wisely and choose this product first vs sampling other testers only to get to this product after trial and error.

Super easy and well worth the money. It is an elegant device that takes the guess work out of reading a refractometer or especially a hydrometer.

I love this product, it is really easy to use. Correct salinity levels are critical in this hobby. Worth to buy!

The new Milwaukee MA887 Seawater Digital Refractometer encompasses 3 different types of user selected scales for the measurement of seawater providing for a much more precise evaluation. Each scale is temperature compensated.

PPT - The old standard of Parts Per Thousand of saturated salt. This is the oldest of the 3 seawater measurements scales

S.G. - The current standard of Specific Gravity hydrometers and refractometers.

The Milwaukee Instruments MA887 digital refractometer is easy to calibrate and easy to read and provides highest accuracy possible for the measurement of seawater 3 specific scales. This is the type of accuracy demanded by today’s professionals and Milwaukee Instruments delivers.
